I've had occasions when utmp gets silly, though not for ages.

Does this make sense? Which other commands I can use > to see what's going on? utmp(5) makes good bedtime reading :) /var/log/wtmp can get messed up sometimes too, especially if you're logged in when periodic(8) monthly rotates it, but tools include: % last smithi ttyp5 dolores Mon Feb 2 15:52 - 15:57 (00:05) wtmp begins Mon Feb 2 15:52:27 EST 2009 !last -f /var/log/wtmp.0 smithi ttyp5 rock.-----.org Mon Jan 26 19:37 - 23:17 (03:40) smithi ttyp5 rock.-----.org Thu Jan 15 21:30 - 21:45 (00:14) smithi ttyp5 rock.-----.org Thu Jan 15 18:04 - 18:05 (00:00) smithi ttyp5 rock.-----.org Thu Jan 15 18:01 - 18:03 (00:01) somebody ftp ww.xxx.yyy.zz Thu Jan 1 10:47 - 10:50 (00:03) [..] % who smithi ttyv7 Dec 12 02:39 % who /var/log/wtmp.0 [..] somebody ftp61687 Jan 1 10:47 (ww.xxx.yyy.zz) smithi ttyp5 Jan 15 18:01 (rock.-----.org) smithi ttyp5 Jan 15 18:04 (rock.-----.org) smithi ttyp5 Jan 15 21:30 (rock.-----.org) smithi ttyp5 Jan 26 19:37 (rock.-----.org) % who am i smithi ttyp4 Feb 18 18:16 % tty /dev/ttyp4 you could try opening enough xterms (ono) so your ttyp5 is used, then exit them cleanly? Failing that, you can boot single user, mount /var, rm /var/run/utmp, hit ^D (or reboot) .. IIRC I had to do that once; not sure what happens if you rm /var/run/utmp while running multi-user! :) cheers, Ian _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
